Taking a typical continental reservoir group as an example, this paper introduces research ideas of the modern reservoir modeling technology for the geological features of target lasyers, using facies-controlled reservoir modeling approach, by structural model, sand body modeling and petrophysical modeling, establishment of a three-dimensional, quantitative reservoir geological model is finished, each level modeling created constraints impact on secondary modeling. Actual production shows that reservoir geological modeling techniques provides the necessary and reliable geological basis for the scientific reservoir evaluation, reservoir simulation, dynamic prediction and optimization of program.
